Maciek is an architect/(lead) developer having more than 12 years of experience in IT – but his roles vary from analysis to deployment. He is mainly interested in JVM (Scala in particular)
His main fields of interest are functional programming, stream processing systems (Akka, Kafka, Flink) and integration.
He also like to give talks at conferences – Confitura, HeapCon, Devoxx just to name a few.


Stream Processing for Analysts with Flink and Nussknacker

Analyzing and gaining insights from large amounts of data is one thing. Doing it in real time is a whole different business.
There quite a few advanced stream processing engines, Apache Flink is one the most widely used. However, designing, testing and deploying streaming jobs usually demand development skills – it’s not so easy for analysts or business people.

When Flink was introduced in one the largest Polish telcoms (which is used for real time marketing and fraud detection there), Maciek and his team decided to build open source project – Nussknacker – to make it easier for non-programmers to use all Flink power.

Maciek will tell about it and show what they’ve built. The talk will be based on real-world examples – from simple filterings to aggregations and model serving.
